Embodiment 1

[0076] The calorie metering and cost apportionment method of the present invention can be understood as: it is based on the optimization of the existing on-off time area method, which specifically includes the following steps:

[0077] S1. Install a main cooling and heating meter for measuring the total cooling and heating value of the building at the heating inlet or cooling inlet of a building;

[0078] S2. Install a temperature controller in each user room to set and measure the indoor temperature;

[0079] S2-1. Install a return water temperature sensor on the household return water pipeline 4 of each user to measure the return water temperature; install a water supply temperature sensor on the household water supply pipeline 3 of each user to measure the water supply temperature;

[0080] S3. A flow meter is installed on the household water supply pipeline 3 or the household return water pipeline 4 to measure the inflow flow;

[0081] S4. Install control valves on the ho...

Embodiment 2

[0096] The method for optimizing based on the existing temperature method of the present invention has basically the same steps as the method for optimizing based on the existing on-off time-area method in method embodiment 1. The cold and heat metering and cost apportionment method of the present invention can be understood as: the apportionment calculation formula of the heat supply of each user is based on the existing temperature method, and the parameters such as the fluid flow rate and the temperature difference between the supply and return water are introduced for correction. , thus improving the accuracy and reliability of the existing temperature method for heat cost apportionment calculation.

Embodiment 3

[0098] The steps of the optimization method based on the existing flow temperature method of the present invention are basically the same as the optimization method based on the existing on-off time-area method in method embodiment 1. The cooling and heat metering and cost apportionment method of the present invention can be understood as: the apportionment calculation formula of the heat supply of each user is a calculation formula including the user flow rate and the parameters of the temperature difference between the supply and return water, which eliminates the error caused by the change of the flow rate, Improves the accuracy and reliability of heat cost apportionment calculations for the existing flow temperature method.

[0099] Such as Figure 4 As shown, the cold and heat metering and cost sharing method of the present invention, based on accurate flow measurement, not only collects the on-off time signal of the valve and the indoor temperature signal, but also colle...

Abstract

The invention provides a cold and heat metering control and cost allocation system, comprising a main cold and heat meter for measuring total cold and heat values of a building and a plurality of user metering devices. Each user metering device comprises a temperature control instrument for setting and measuring an indoor temperature, a flow meter for measuring a water inlet flow, a control valve for switching on or off sub-user water supply pipelines, and a data processor for receiving and processing various data and controlling the control switch to be switched on and off. The invention provides a cold and heat metering control and cost allocation method, comprising the following steps of: mounting the main cold and heat meter on the building; mounting a plurality of the user metering devices and the data processor; and calculating the refrigerating amount or the heat supply amount of a user by the data processor according to the received various data and the data of the main cold and heat meter. The cold and heat metering control and cost allocation system and method provided by the invention have the advantages of accuracy in metering and low cost.

Description

technical field [0001] The invention relates to a cooling and heat metering control and cost sharing system and method. Background technique [0002] At present, the heat measurement and cost methods used in our country mainly include: household heat meter method, radiator heat distribution table method, on-off time area method, flow temperature method and temperature method. [0003] The household heat meter method is to install an ultrasonic heat meter or a mechanical heat meter on the user's thermal pipeline, and the heat meter directly measures the consumed heat. However, the ultrasonic heat meter among them is expensive, and its application in general residential buildings is limited; the mechanical heat meter is also difficult to popularize due to problems such as blockage due to poor water quality. The radiator heat allocation table method is a method of measuring heat by measuring the heat dissipation of the user's radiator, which cannot solve the problem of inaccur...
